LUBRICATING DEVICE;

Application filed October 31, 1921. Serial No. 511,566.

To all whom it may concern:

Be it known that I, Lac M. HALE, a citizen of the United States. and aresident of the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and useful Improvements inLubricating Devices, of which the following is a specification.

My invention relates to lubricating devices, and has for its object theprovision of a construction of this character which is particularlyadapted for application to ,so-

[called overhead valves of internal combustion engines, and which willsupply lubricant to the moving parts of such valves which are ordinarilyunlubricated.

Another object of the invention is to provide an oil reservoir havingmeans for maintainingthe flow of lubricant therefrom for a predeterminedperiod before exhaustion of said reservoir.

Other objects will appear hereinafter.

The invention consists in the combination and arrangements of partshereinafter described and claimed.

The invention willbe best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a side elevation of the invention in operative position.

Fig. 2 is a sectional side view of the invention, and

Fig. 3 is a top plan view of the invention showing the interior of thereservoir.

The so-called overhead valves of internal combustion engines areordinarily insufliciently lubricated, and my invention is designed tosupplement the lubricating: means ordinarily employed, and to provideadditional means for lubricating parts of said valves.

In the drawings 1 represents an overhead valve rocker arm of anysuitable construc tion. pivoted on a supporting stud 2, having providedat one end a comlimiation grease cup and bearing 3. which 15 adapted toaccommodat e and lubricate one end of the valve stem 4. The other end ofthe arm 1 engages the upper end or the valve stem 5, on which is mountedthe usual spring 6 which abuts against a seat 7 provided in cylinderblock 8. The parts above descr i are all well known and of themselves0121" no part of the present invention. A

My invention consists of a lubricating attachment adapted to be appliedto the rocker arm 1. The device has a cup or reservoir 10 having aconical end 11, which is provided with an aperture 12, said aperturehaving an interior annular rib 13 surrounding same.

Mounted on the cup 10 is a spout 14:, which communicates at its innerend with the cup 10, the outer end thereof being preferably downwardlycurved and disposed over the end of the rocker arm 1 and the valve stem5,. as shown in Fig. 1. The attachment is preferably secured to therocker arm by a suitablebraoket 15 which may be held in position on saidarm by bolts extending therethrough.

Disposed in the bottom of the cup are wicks 16 and 17, the end of thewick 16 projecting out of the aperture 12 a suitable distance, and thewick 17 extending through the spout and projecting from the end thereofa suitable distance, as shown in Fig. 2. A pad, or pads, 18 of felt orother absorbent material are preferably placed in the cup, as shown, toprevent spilling or too rapi feeding of the oil through the wicks. Theconstruction is such that when in position on the rocker arm of thevalve, and the reservoir 10 is filled with lubricant, the flow of suchlubricant through the aperture 12 and the spout 14 will continue acertain period before the reservoir-"10 is exhausted. For instance, thereservoir may be supplied with such quantity of lubricant in the morning that b night all of the lubricant will have passe from thereservoir, thereby cutting off the supply of oil when the machine isstanding over night. If desired, suitable means may be employed forpermitting or cutting off the fiow. of lubricant from the device at willin order to obviate the necessitv for daily filling.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect. this is capable ovariation and modification without departinn from the spirit of theinvention. 1', therefore, do not wish to be limited to the precisedetails of the construction set forth, but desire to avail myself ofsuch variations and modifications as come within the scope of theappended claims.

Having described my invention, what I ciaim as new and desire to secureby Letters Patent, is

" in combination with a valve havingaarm; a lubricating device mountedon two 3. In combination With a valve having a v rocker arm; alubricating device mounted on said arm and having a reservoir, therebeing on opening in said reservoir disposed adjacent one end of saidarm; and an extension communicating with said reservoir disposedadjacent thejopposite end of said.

rocker arm.

4. In combination with a valve having a rocker arm; a lubricating,device mounted on said arm and having a reservoir, there being anopening in said reservoir disposed adjacent one end of said arm; anextension communicating with said reservoir disposed adjacent theopposite end of said rocker arm; and absorbent means in said reservoir,said aperture and said extension for gradually feeding the lubricanttherethrough.

5. In combination with a valve having a rocker arm; a lubricating devicemounted on said arm and having a reservoir, there being an opening insaid reservoir disposed adjacent one end of said arm; an extensioncommunicating with said reservoir and disposed adjacent the opposite endof said rocker arm; absorbent means in said reservoir; and a wick insaid aperture and said extension.

6. A lubricating device having an open reservoir, there being anaperture therein; a spout communicating with said reservoir;

insane awick in said reservoir having one end disposed in said apertureand the other end disposed in said spout and its intermediate por tioncoiled in said reservoir; and absorbent means substantially filling saidreservoir.

7. A lubricating device having a reservoir, therebeing an openingtherein; a spout communicating with said reservoir; a wick in saidreservoir having one end disposed in said opening and the other enddisposed in said spout, and having its intermediate portion coiled insaid reservoir,

8. In combination with a valve having a rocker arm; a lubricating devicemounted on said rocker arm and having a reservoir disposed at one endthereof, there being an aperture in said reservoir; a spout mounted onand communicating with said reservoir and having its outer end disposedabove the other end of said rocker arm; and absorbent means disposed insaid aperture and said spout for regulating the flow of lubricanttherethrough.

9. In combination with a valve having a rocker arm; a lubricating devicemounted on said rocker arm and having a reservoir disposed at one endthereof there being an aperture in said reservoir; an annular interiorrib surrounding said aperture; a spout mounted on and communicating withsaid reservoir and having its outer end disposedabove the other end ofsaid rocker arm; wicks disposed in said aperture and said spout forregulating the flow of lubricant therethrough; and absorbent materialdisposed in said reservoir to retain lubricant therein.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnemes.
